This invention relates to sewing machine attachments. More particularly,it relates to the type of sewing machine attachment adapted for use as agauge for rows of stitching.

One of the objects of myinvention is to provide a sewing machine gaugeof the character described, designed to quickly sew a plurality of-parallel, equally spaced rows of stitching on a material in acontinuous operation without the necessity of having to start each newrow of stitching at the top and of breaking the thread after each row.

Another object of my invention is to provide a stitching gauge of thecharacter described which may be readily attached to any standard typeof presser foot generally employed.

Still another object of my invention is to provide a double sided,symmetrically arranged stitching gauge of the character described whichmay be used for gauging a row of stitching on either side of the needle,or on both sides at the same time, if desired.

A still further object of my invention is to provide a stitching gaugeof the character described 7 which is constructed of a single sheet offlat I tures of construction, combinations of elements; and arrangementof parts which will be exemplified in the construction hereinafterdescribed, and of which the scope of application will be indicated inthe following claims.

In the accompanying drawing, in which is shown one of the variouspossible embodiments of this invention,

In the sewing machine stitching art, it is often desired to sew a row ofstitches parallel to an edge of a garment or to the edge of a piece ofmaterial. Also for decorative purposesit is often desired to sew aplurality of equally spaced parallel rows of stitching. In the sewing.of such rows of stitching, it is necessary to employ some sort ofgauging means if the rows of stitching are to be straight and parallel.l-leretofore, complicated and intricate gauge mechanisms were employed,each of which required a specially designed presser foot for attachment.In previous gauge constructions, when it was desired during" the courseof the operation of the sewing marows of stitching, for then it wasfound that much time was lost in having to starteach row of stitching atthe top. This procedure also made it necessary to break the thread aftereach ro By my invention I have provided a simple sewing machine gaugedevice, which is quickly attachable to any standard type of presserfoot,

and by means of which a plurality of equally spaced parallel rows ofstitching may be sewn without any of the above described disadvantages.

Referring now in detail to the drawing, there 5 prising thesubstantially rectangular-portions l3,

l4 and 15, the portions M and-l5 being interconnected with the portionit by a-neck portion l6.

, To construct the gauge, the portion is is rolled over to form a hollowpocket member H, which may be substantially rectangular in crosssection, as clearly shown in Figs. 4 and 5. The area where the portions14 and i5 are joined, such as is indicated by the dotted line it of Fig.6, is bent so as to have a rounded corner and is adapted to liealongside a side wall Ila of the member Another disadvantage inherent inH, as shown in Fig. 5. It is noted that the portion I4 now lies in aplane parallel to and slightly above the top wall ill: of the pocket IT.The portion [3 is then folded over inwardly toward the pocket [1, sothat the neck portion 55 forms a wall [6a (see Fig. 3) closing off oneend of the pocket I7. After folding as just described, the said portion[3 is adapted to overlie adjacent the top wall Nb of the pocket ll, saidportion 13 then being in the same plane and in symmetrical alignmentwith the portion Hi.

My improved gauge device as above described is designed to be attachedto any standard type of presser foot I l by having the pocket member I!telescopically received on the longer extension Ila of the presser foot,as clearly shown in Figs. 1 to 5 of the drawing. Ihe gauge H] is held inresilient engagement on the presser foot by means of the slightlyrounded corner caused by bending the member M on the fold line l3, aspreviously described, because of the fact that the shorter extension Nbof the presser foot H is adapted to frictionally engage the underside ofthe portion !3 at the above mentioned area I8, as illustrated in Fig. 5.

It is thus seen that the gauge device may be easily and quickly attachedto the presser foot and resiliently held thereon. It is noted from 4 ofthe drawing that the pocket member H is of lesser length than the widthof the portions l3 and M. This is designed so that the pocket member 57!will not contact the material underneath the presser foot.

The operation of my improved gauge will now be described. In Figs. 1 and2 there is shown a piece of material M on which it is desired to sew aplurality of parallel equally spaced rows of stitching. In Fig. l a rowof stitching 28 has been started on the material M, said material movingin the direction shown by the arrow, with the distance from the row ofstitching 20 to the edge E of the material M being gauged by the edge Aof the gauge portion 53 to provide the row of stitching 20 parallel tothe edge E. When the row of stitching 26 has been completed, thematerial M is then turned, as shown in Fig. 2, and in a continuoussewing operation and without breaking the thread, a second row ofstitching 2i is then started, sewn in the opposite direction to thestitching of the row 26, but this time, since the material M has beenturned around, the second row 2i is gauged on the previously made row2:; by means, this time, of the edge B of the gauge portion l4. If it isdesired to stitch a third parallel row to the rows 20 and 2!, the sameprocess would be repeated; that is, after the completion of thestitching of row 2 i, the material would be turned around again and thethird row of stitching would be gauged on the row 2! by the edge A ofthe gauge portion l3.

From the above described operation, the advantage of a double-sidedstitching gauge, each side being the same distance, is readily seen. Itis also apparent that a greater saving of time is effected by myinvention than the type of gauge heretofore employed, which was usuallya one-sided gauge and had to be readjusted after each row of stitching,since the gauging was always done from the edge of the material.

The type of double-sided gauge illustrated in Figs. 1 to 6 is adaptedfor the gauging of only one predetermined distance, such as A", or A2,etc., between rows of stitching. In Fig. '7, however, I have shown amodified form of construction of a double-sided gauge device IO, whichis adaptable for more than one size. In this form, the outer gaugingedges of the portions I 3' and M are correspondingly stepped to providedifferent gauging distances.

In Fig. 8 I have shown still another modified form ID" of my gaugedevice, which is adapted for use in sewing a row of stitches parallel toa turned edge of a garment, such as an overcoat lapel, etc. and it isseen that in this case the gauge portion I4" is provided with adownturned edge 30, which is adapted to ride along the edge of the saidlapel. While in this form of device, I have illustrated a single-sidedgauge, since in most cases this type of gauge would be used only forsewing a single line of stitching parallel to an edge, nevertheless, itis understood that the type of gauge illustrated in Fig. 8 may also beof double-sized construction similar to the gauge l0,

It will thus be seen that there is provided a device in which theseveral objects of this invention are achieved, and which is welladapted to meet the conditions of practical use.

As various possible embodiments might be made of the above invention,and as various changes might be made in the embodiments above set forth,it is to be understood that all matter herein set forth or shown in theaccompanying drawing is to be interpreted as illustrative and not in alimiting sense.

Having thus described my invention, I claim as new and desire to secureby Letters Patent:
